These numbers may suffer from a number of biases and shouldn't be considered in any definitive.
- Not all new links are captured by the IRC feed WebCiteBOT relies on during busy times
- If either WebCiteBOT or the IRC feed it relies on goes down for any period of time, that day will be way under reported
- Previously, if someone added more than about 4 (depending on length) URLs at once, not all links will be captured and counted. This was fixed sometime in 2011.
- If someone repeatedly re-adds to same link, it will be counted over and over again no matter how quickly it is removed again
- If a vandal blanks a portion of a page that contained one or more URLs, the links will sometimes be counted as "new" when the vandalism is reverted.
